I just have to vent, but since I don't want to embarrass either my office or yours, let's keep this anonymous.

I had an associate (!) in my firm ask me why she couldn't seem to find a copy of the Barcelona building code published in English anywhere. (I responded that I doubted anyone could find a Spanish-language version of the Chicago building code, but she didn't get the comparison) Yale-educated architect, by the way....

Someone in a former office once directed a drafter to detail a 4-inch stainless stud wall. He did not understand the difference between metal studs and stainless steel studs.

From a couple of years ago (from someone working on a project in coastal Louisianna):

"Have you spec'ed anything on hurricane-resistant glazing before? We may need to add that to the project. Would we just make the windows hurricane resistant that face the direction of the wind or would all the windows need to be hurricane resistant?"

Several years ago, a partner in our firm asked me why we couldn't prepare "standard" specifications for various project types that we could use over and over, without editing, so they wouldn't have to budget so much money for spec preparation. My reply?

If we did that, we'd have to call them "Generalizations" instead of "Specifications". :-)

He got my drift and has never mentioned it again.

For the same reason one can't prepare "standard" drawings...that can be used over and over...without editing...so they don't have to budget so much for design!

I had the principal of a firm respond to my question about the finish on aluminum storefront framing by saying, "We want a Kynar anodized finish." I explained that there is a fundamental difference between the painted finish based on a fluorpolmer resin ("Kynar") and an anodic metallic finish. His response was, "I don't keep up with new technologies." He's about 40 years old.

I love that! the idea that we could have a requirement in the specs that says "no matter what you see on the drawings, do it this way...."

(actually my boss has told me to do that in a few cases -- "put something in the specs to cover this, so no matter what is on the drawings....")

Drinking Fountains in Men's Restrooms.

Can be done but must have the rim of the sink minimum 60" above finished floor.

The men's restroom in the BeerStube at the Whitefish ski area in Montana has the lav (singular) mounted at least 48" AFF.

Bradley foot activated hand wash sinks are also at risk in both men's and women's washrooms if the venue is on a university campus, during frosh week, during a concert with beer vendors.

After stating in an email to the civil engineer on a project that they are not to include the geotechnical report as a contract document (they seem to always do that), this is what I got in return, just a few moments ago, regarding their specifications:

"I still need to work thru how the pavement sections will be addressed since the soils report is not considered a contract document, who is ultimately responsible for the pavement section design?"

And people complain that architects are trying to limit their responsibility by passing some of the work onto others.

This was not a question - but it was quite silly. I once worked for a corporate client who did not want to spend money on field checking. Instead, they wanted the A/E firms to rely on the existing drawings that they had available for each site location and to use their standard general notes. One of their corporate standard general notes read as follows: "The contractor is responsible to provide everything that is indicated on the drawings including items that are shown as existing that are not there". They truly expected that if a door, toilet room or "whatever" was shown as existing, and it was not actually there that the contractor had to provide it. They even admonished me for field checking a project that was within close driving range.

My first post architecture education home was an apartment in San Francisco I shared with an also just graduated architecture major from Yale.

As I was the graduate from U of Oregon, which seemed to imply real hands-on experience, I was put in charge of building out our photo darkroom in the attic.

Picking a board off the floor one day he asked me what this was, and when I explained, he said with a note of wonder in his voice, "So THAT'S a 2 by 4!"

We were designing a hospital in a large California city. We had a meeting with a city contract specialist to go over contract requirements. Everything needed to be competively bid. Two of their chief concerns:

1. Provide an alternate source to code compliance than the California Building Code.

2. Provide and alternate source to issue permits than OSHPD (Office of Statewide Health Planning and Development).

Another one of my favorites, from several years ago:

"I need a spec for a ballasted roof system. The aggregates on the roof will be provided by a landscape contractor and not the roof contractor. Can you provide me with this? Don't we have one that is already formatted from a previous job?"

I sent back a few silly questions of my own:

-- What membrane material?
-- What is the basis of design product / system?
-- Manufacturer?
-- Reinforced membrane or unreinforced?
-- Overall roof assembly?
-- What is exterior fire-test exposure class?
-- Type of insulation?
-- Thickness / R-value of insulation?
-- Type of deck and substrate?
-- What is roof slope?
-- Is insulation uniform thickness or tapered?
-- Wind uplift resistance requirements?
-- Who is Owner's insurance carrier?
-- Does overall system have to comply with FM Global or UL, or other?
-- Perimeter condition - parapet or roof edge/facia?
-- Internal drains or scuppers or gutters?
-- Has structural engineer verified in writing that roof structure (originally designed for modified bit roof) can carry the extra weight of the ballast?
-- Will the manufacturer warrant the roofing system if someone else's ballast is used?
-- Will the manufacturer warrant the system if someone else other than their approved applicator installs the ballast?
-- What is the desired warranty duration?

Never heard from him again.

Not a question, but showing silliness is everywhere;

Latest News-In front of 5 lawyers, a registered/licensed architect, state certified code inspector, photographer, and statement recorder...the local inspector insisted as per IRC 1102.1.10...all vertical joints between immediately adjacent and nailed together studs, must be caulked to prevent air movement. All these joints are completely covered by OSB/Tyvek on the outside and drywall/low perm primer on the inside. In most cases, the thinnest feeler gauge could not be forced between the studs. The joints where the ends of the studs meet the plates was not addressed. There was no mention of the joint between the 2x6 top plates or bottom plate/floor joint, either. The local inspector pointed to the pairs of studs holding up headers over doors and windows and corners where multiple studs are nailed together. Individual studs, 16" oc were not mentioned as air movement sources.

See Wikipedia, "Economy of California."

Depending upon the source, if California was ranked as a separate country it would be economically between the 7th and 10th largest in the world.

Kaliphonia (guvenator's pronounciation): quirky, kooky, too fast-paced, getting too crowded, overly materialistic, culturally and socially diverse and very busy for commercial and institutional architects and engineers. It's the future, for better or worse.

What you are about to read is for real. It is an excerpt from Hermes of Paris requirements for what they call ONE-SITE MEASUREMENT. I quote:

"You might think that with all the regulations and specifications we have, provided one meter measured in Paris will be the same length as one meter measured in Valencia, Boston or Munich. But unfortunately this is not the case. In other words "one meter" at one site will not necessarily equal "one meter" at another.

Or put another way: if five different workers measure the same area of a single site, you will get five different lengths. One very good way to demonstrate to your contractors the kind of precision we require is to ask their foreman to bring a yardstick measure to the first meeting.
Then put the zero end of all yardsticks adjacent to each other.

You'll be amused when you see the worker's amazement of what happens at the other end of the yardstick; there is a discrepancy in the gap at the ends of the yardsticks.

So imagaine how inaccurate a measurement that extends over 25 or more meters could be. [The fun part begins here; my words]. So you need to designate one person to be in charge of all the main measurements at the site.

This person should be the surveyor who surveyed the site before construction began. The contrcctor will like the idea of having a measurement coordinator and will agree to share the costs of the surveyor by the various subcontractors according to the proportion of the overall work each subcontractor is responsible for. This should be stipulated in the contract. The surveyor has to attach all axis lines and important points secured on the site.

Also the planned finished level has to be marked carefully. This procedure is especially important when you have more than one floor/level connected by a lift/elevator or stairs.

[Now for the best part]

All contractors are required to produce precise fit and finish devoid of any tolerances of any kind. Nor should the proposal/bid and contracts allow for any tolerances of any kind either.

If any tolerances are allowed for in the contract, the contractor will try to claim that he was just applying industry-standard tolerances. The latter differ from those stipulated in local regulations, but they are completely unaccpetable in a Hermes boutique."

Whew!

Sure there will be a discrepancy if you try to measure a meter with a yardstick--along the lines of 3.37 inches.

Even if they don't have lasers in France--do they have metersticks?

For a project I'm currently working on, I asked my client (the architect) to obtain from the structural engineer the movement capability for a proposed expansion joint that was to have a fire-resistance rating of 2 hours. His response? (Mark Gilligan, you'll like this)

"I'm going to stick with my original recommendation for a 1" structural gap. This means that we need to allow for +/-1" movement in each direction."

Anybody know where I can find a fire-resistive joint assembly that has 200% movement capability?

Nathan, C-S provides a lot of covers, but they do not provide any with 200% movement capability. And, since it's a fire-resistance-rated floor, if the the gap is 1 inch and the movement is +/- 1 inch, then the fire barrier material in the joint would have to be capable of being compressed to nothing--zero inches. A physical impossiblity.

The most you can ask for (and UL lists) is 100% movement capability (50% compression and 50% extension), which means for a 1-inch gap, the movement would be +/- 1/2 inch, or 1 inch overall.

First I believe the term "structural gap" is potentially misleading. My practice is to state the amount of movement needed and let the Architect select the cover with input from the manufacturer. The joint hardware always takes up some space but typically we do much better than 50%.

You should also verify how much movement parallel to the joint needs to be accommodated.

Out here in California 1" of movement is very minor. At a 5th story bridge between buildings I designed a system to accommodate 24" in each direction.

Talk to the manufacturers rep regarding fire ratings. One approach is to drape a flexible assembly underneath the floor between the two sides. This may make a 2 hour rating possible.

If you can get the filler out of the joint then you can do much better than 50% movement.

We are in the process of designing a 24 inch joint on one of our projects here in CA
This is a huge gap in my estimation. We are working with C/S as well.

As for Nathan - I agree with Ron.
The NyQuil has apparent affected his spelling as well.
